Most of my music is in ogg format, but I can't for the life of me work out how to get them automagically transcoded to mp3s for the Xbox 360.

I've tried changing the any-mp3.desc file to use sox, creating sox-ogg-mp3.desc and ogg-mp3.desc files in cgi-bin, adding MT lines to the client.db. Background transcoding is available to be switched on, but I don't want to double up the files.

Videos play OK, and the few mp3s I have work fine... but it'd be nice to get to the rest of the music.
